I haven't seen you mention anything about your PH. From looking at your pictures, you appear to have a low PH issue going on with your plants.
I have not tried to sample my runoff but I will. Input is 5.5-5.6 when I mix the feed in RO water. Rises to 5.8-5.9 by day three when I finish the rez. Meter is a Blue Lab Guardian calibrated each Monday whether it needs it or not. I have a Blue Lab hand held that I'm going to cross check the Guardian with.
